Hi Charles

Yes, your workaround looks good and won't cause problems for you. It seems you have understood and dealt with this bug correctly.

Best regards,

Simon

Hi Simon, thanks for the response.

That ticket looks like it's confirming the following statement:

"When the watchdog is enabled, nrf_drv_clock_lfclk_stop() will hang forever."

If that's an errata, we can live with it; we're already past it. I just want to confirm that my reading of the of the other bug is correct, and that my workaround is endorsed by Nordic.

Hi Charles

Glad to hear you found a workaround!

Are you using the WatchDog? In that case we have seen this issue before in threads like this.

Best regards,

Simon

(to be explicit, we use app_timer extensively, we just don't manually configure lfclk or RTC1 and let nRF SDK + SD handle it all)
